Good but needs work – Find The Difference 2 (Hidden Objects Game) Review

I have fun playing this but some of the functions don’t seem to work. I have come to a point where the game will not allow me to purchase more coins for hints. I ended up skipping over one puzzle because I was stuck and had no more hints. After the next puzzle, I tried to go back to finish the previous puzzle but can’t find a way to do that. Please work out the kinks!
